| Abstract: |
| The influences of Zn and Ag elements on the mechanical properties and microstructures of extruded mono-phase biomedical magnesium alloys were investigated via scanning electron microscopy, electron backscatter diffraction (EBSD) and X-ray diffraction technique (XRD). With the addition of 3wt.% Zn, the yield tensile strength (YTS) and ultimate tensile strength (UTS) of Mg-3Zn alloys are increased from 101 MPa to 121 MPa and from 188 MPa to 228 MPa, respectively. Whereas, the elongation of Mg-3Zn alloys is decreased from 17.86% to 12.57%. The YTS and UTS of Mg-3Zn-0.5Ag alloys are almost same as that of Mg-3Zn alloys. While the elongation of Mg-3Zn-0.5Ag alloys is increased from 12.57 to 14.77% with the addition of Ag into Mg-3Zn alloys. EBSD and XRD characterization implies that the grain size of Mg-3Zn and Mg-3Zn-0.5Ag alloys are much larger than that of pure Mg, whereas the texture of alloys is more than pure Mg, which indicates that the deformation mechanism are changed with addition of Zn and Ag elements. |
